Description
Reliable control of fire dampers
The Belimo BF24/500 fire damper actuator is specially designed for the automatic opening and closing of fire dampers in ventilation and air conditioning systems. In the event of a safety signal or power interruption, the safety function moves the fire damper to the designated position. With a torque of 18 Nm, the execution is matched to a suitable damper size and mechanical load.
Together with a suitable fire damper, the actuator forms part of the building’s fire safety concept. The selected voltage, runtime, feedback and thermal activation are matched to the damper and the installation control.
